Description

PRESERVATIVE FREE BIMATOPROST SOLUTIONS
By Inventors: Sukhon Likitlersuang, Ajay Parashar,
Chetan P. Pujara, and William F. Kelly
CROSS REFERENCE TO RELATED APPLICATIONS
This Application claims the benefit of US Provisional Patent Application Serial No. 61/368,688 which was filed on July 29, 2010 and is hereby incorporated by reference in its entirety.
FIELD OF THE INVENTION
The present application is directed to preservative-free formulations of bimatoprost.
BACKGROUND OF THE INVENTION
Bimatoprost is a prostamide, a synthetic analog of prostaglandin F2a (PGF2a) with potent ocular hypotensive activity. Bimatoprost lowers intraocular pressure (IOP) in patients with glaucoma or ocular hypertension by increasing outflow of aqueous humor through both the trabecular meshwork and uveoscleral routes. Use of preservative containing eye drops has been implicated in the development or worsening of ocular surface disease. Management of open angle glaucoma and ocular hypertension require long term treatment with eye drops containing preservatives. Symptoms and signs of ocular surface disease such as ocular surface breakdown, irritation, burning, foreign body sensation, dryness, inadequate quantity of tears etc are prevalent in a large proportion of patients with open angle glaucoma and ocular hypertension.
Compared to eye drops preserved with benzalkonium chloride, preservative-free eye drops induce significantly fewer ocular symptoms and signs of irritation in patients, such as pain or discomfort, foreign body sensation, stinging or burning, and dry eye sensation.
Patients experiencing hypersensitivity reactions with benzalkonium chloride cannot use the commercial bimatoprost product containing benzalkonium chloride such as LUMIGAN which is preserved with 0.005% w/v benzalkonium chloride. Benzalkonium chloride also may be absorbed by the soft contact lenses therefore patients wearing soft contact lenses are advised to remove lenses prior to administration and wait at least 15 minutes before reinserting them. SUMMARY OF THE INVENTION
The present invention is directed to bimatoprost formulations (e.g., solutions) without benzalkonium chloride which are superior from a safety, tolerability and patient compliance standpoint while maintaining and/or improving its efficacy of IOP lowering and be available for use by patients hypersensitive to benzalkonium chloride and be convenient for patients wearing soft contact lenses.
Bimatoprost ophthalmic solution without preservative is a clear, isotonic, sterile solution. The drug product contains bimatoprost as the active ingredient. The inactive ingredients are tonicity and buffer agents, and purified water. Suitable buffers such as sodium phosphate dibasic heptahydrate and citric acid monohydrate and suitable tonicity agents such as sodium chloride may be included. The final solution would be an aqueous solution having a pH value within the range of about 7 to 8 , preferably 7.3 and osmolality in range of 280-370 mOsmol/kg.
The present invention can be made generally according to the teachings of US Patent No. 5,688,819, which is hereby incorporated by reference in its entirety.
Some of the embodiments of the present invention are as follows: ) A preservative free bimatoprost composition for lowering intraocular pressure in a patient comprising the following formulation: about 0.03% w/v bimatoprost; about 0.268% w/v sodium phosphate heptahydrate; about 0.014 % w/v citric acid monohydrate; about 0.83% w/v sodium chloride; water and having a pH of about 7.3. ) A preservative free bimatoprost composition for lowering intraocular pressure in a human patient comprising the following formulation: 0.03% w/v bimatoprost; 0.268% w/v sodium phosphate heptahydrate; 0.014 % w/v citric acid monohydrate; 0.83% w/v sodium chloride; water, hydrochloric acid, sodium hydroxide and having a pH of about 7.3. ) The bimatoprost composition of paragraphs 1 and 2 wherein the composition is a solution and is useful for treating glaucoma. ) The bimatoprost composition of claim 3 wherein the solution is contained in a unit dose kit form. ) The bimatoprost composition of paragraphs 1 - 4 wherein the composition is a solution and is applied once a day to each eye. ) The bimatoprost solution of paragraphs 1 - 4 wherein the composition is a solution and is applied twice a day to each eye. ) The bimatoprost composition of claim 1 wherein the composition is a solution and has greater bioavailability of bimatoprost in the eye of the patient with fewer side-effects than bimatoprost preserved with benzalkonium chloride. ) The composition of paragraph 1 wherein the composition may be a solution, emulsion, dispersion, suspension, reverse emulsion and microemulsion. ) The composition of paragraph 1 wherein the composition is contained in a unit-dose vial. 0) The composition of paragraph 1 wherein the composition is contained in a multi-dose vial which has anti-preservative properties such as metal-ions imbedded in its dispensing tip. 1) The composition of paragraph 12 wherein the metal ions are silver ions
DETAILED DESCRIPTION OF THE INVENTION
One bimatoprost ophthalmic formulation of the present invention without preservative shown in Table- 1.
Table 1 : Example of a bimatoprost ophthalmic solution without preservative according to the present invention:
The present invention is directed to the same bimatoprost formulation as commercially available LUMIGAN 0.03 but without benzalkonium chloride as a preservative and in unit-dose or multi-dose form. As a result of the removal of benzalkonium chloride, the present invention results in greater bioavailability of the active ingredient bimatoprost in the eye without the unwanted side- effects associated with the preservative benzalkonium chloride such as hyperemia. This results in a formulation with the same or improved efficacy of the product in lowering IOP per dosage unit, fewer side-effects and superior patient compliance. Other side effects which may be avoided include visual disturbance, ocular burning, foreign, body sensation, eye pain, blepharitis, cataract, superficial punctate keratitis, eyelid erythema, ocular irritation, eye discharge, tearing, photophobia, allergic conjunctivitis, asthenopia, conjunctival edema, conjunctival hemorrhage, and intraocular inflammation.
